That's interesting. I'm on Linux. I tried running druntime's unittests
some days ago and I had a very similar problem. I assumed this must be
some local setup problem. But now I see that the problem must be
somewhere else. I have the same undefined references
_D4core5bitop3bsfFNaNbkZi as you.

How come that the auto-tester (http://d.puremagic.com/test-results/)
does not have this problem? Does the auto-tester use the dmd it is
building?
